Application October 9, 1944, Serial No. 557,743

7 Claims.

This invention relates to devices for restraining patients who undergo anesthesia and/ or surgery.

In many cases of surgery and particularly dental surgery, the patient will react nervously to the anesthetic and make it difficult for the surgeon to properly execute his work.

In my prior Patent Number 2,295,806, issued September 15, 1942, there is disclosed a restraining device for the same purpose. Nervous reactions of this type are particularly prevalent among children but such conditions are also encountered with adult patients.

While the apparatus disclosed in my above mentioned patent is highly effective, it is a general object of this invention to provide a restraining device which is more simple in its structure and application to the patient.

In one form of the invention, I provide means for securing the wrists and holding them against the body with the hands together in simulation of a natural sitting position.

In another form of the invention, I provide means for restraining a reclining patient with the arms held at the sides.

The above and other objects of the invention will more fully appear from the following description made in connection with the accompanying drawing wherein like reference characters refer to the same parts throughout the views, and in which;

Fig. 1 is a partial view of a patient with one form of restrainer applied;

Fig. 2 is a View similar to Fig. 1 with a different embodiment of my invention.

Fig. 3 is a perspective view of the restraining device of Fig. 1; and

Fig. 4 is a perspective view of the restraining device shown in Fig. 2.

In Figs. 1 and 3 there is shown a main body strap 5 which is adapted to encircle the waist or lower trunk portion of the patient. The strap 5 is provided with a buckle Ed at one end thereof, so that the strap can be secured about the patient. Mounted upon the main body strap 5 is a pair of wrist engaging or encircling strap sections 6. These strap sections may be formed of one piece of strap material or they may be of separate pieces having adjacent ends secured to an intermediate portion of the body strap 5 as shown at l.

Adjacent the secured ends 01- the strap sections 6 the main body strap 5 is provided with transversely disposed diagonal elongated apertures 8, through which the free ends 9 of the strap sections 6 can be passed. It should be noted that the diagonally disposed apertures 8 are at angles 2 to each other and that the secured ends of the sections 6 are diagonally connected to the body strap 5, the direction of the line of connection of each section being parallel to the longitudinal direction of the aperture 8 of the respective section.

Adjacent their free ends, the wrist encircling strap sections 6 are provided with socketed fastener heads ill which are adapted to cooperate with fastener members on the body strap 5. The details of the fastener elements are not shown but may conveniently be head and socket snap fasteners such as are manufactured by United- Carr Fastener Corporation of Cambridge, Mass. They can be quickly separated by pulling the free end 9 of each strap section 6 outwardly from the face of the body strap 5 and of course, can be connected by pressing them toward each other in a reverse direction.

The main body belt 5 is adapted to be first placed around the waist or lower body portion of the patient with the wrist encirclin strap sections 6 located at the front of the body. The wrist encircling sections 6 are loosened, by pulling on the free ends 9 of said sections, from the cooperating fastener elements on the main body portion 5. The hands of the patient can then be inserted through the loops formed by the wrist encircling sections 6, which can be drawn through the apertures 8 in the main belt 5 until the wrists of the patient are tightly held in said wrist encircling sections 6. The free ends 9 of the strap sections 6 are then fastened to the main belt 5 by means of the snap fastener members Ill and the arms of the patient are thus tightly held against his body. The position of the patients arms is illustrated in Fig. 1.

By reason of the fact that any pull on the wrist encircling strap sections 6 is transmitted through the main belt apertures 8 and thence along the main body belt 5, any pull or movement exerted by the arms of the patient will be transferred to the snap fasteners H] in a direction normal to the direction of release of said snap fastener. This firmly retains the wrist encircling strap sections 6 and prevents the patient from disconnecting the fastener elements It] from the main body belt 5 through any movement exerted on the loops which comprise the wrist encircling sections 6.

In Figs. 2 and 4 there is shown a modified form of the structure shown in Figs. .1 and 3. There is illustrated, a main body belt H corresponding to the body belt 5 of Figs. 1 and 3. Secured tothe belt I I is a pair of wrist encircling strap sections l2 each having one end secured to the main V main'hodyistraps and H";

strap I I as by stitching I3. Thefree ends of the of the strap sections [2 are spaced apart and the free ends of the straps 52 are directed toward each other. In the device of Figs. 1 and 3, the anchored ends of the strap sections 5 are adjacent each.

other and their free ends 9 extend away from 4 1y tranversely to said main belt and said extending portions of said sections.

2. In a restraining device for anesthesia and.

surgery, a main restraining belt, a pair of wrist encircling belt sections, each of said sections having an end secured to said main belt, said sections having their other ends passed through said main belt in slidable relation thereto at' points adjacent the secured ends of said sections, those portions of said sections between their secured ends and their points of passage through said main belt providing Wrist encircling loops lying closely adjacent to each other, those portions of said seceach other. By reason of the arrangement of the wrist: encircling strap sections 12, it is possible i to placethe main body belt ll about the patient and fasten the strap sections 82 about the wrists with the arms of the patient lying approximately along sides; This structural arrangement is i convenient where the patient is reclining whereasthat shown in Figs; I and 3. is betteradapted for a-person who is seated. in a more or less upright position such as 'he'normally assumes in a dental chair. a

The restraining. devices shown and. described canb'e quickly: ahdea'silyapplied to a patient without causing 'too great a. psychologicalfeffect and while the snap fasteners it and 1 5 are arranged to firmly secure the straps encircling the Wrists,'they"can'be quicklyrele'asedf by the operator by'merely pulling the. free ends 9 and" i5 of thexstrap sections 6 and laoutwardlyffrom the I It should-be'noted.thatiin Figure 1 the apertures 82 in'thei body strap. 5 which are adapted to receivethe wrist encircling strap sections 6,

are placed on a diagonal and that the secured ends of. the'strap sections 6 are similarly positionedi'to cause the strap sections to' assume a comfortable angle relative to the converging arm positionofthepatient as shown in Fig. '1. The devicefof. Figs- 2:.and 4 is provided with apertures l-extendingstraight acriossthe body strap H to" properly positionthe wrist, encircling strap loop sections l z'where the; arms of the patient extend relatively straight along his sides.

Itwill of coursa be understood. that various change "may be madein the form, details, arrangement and proportion to the various parts without departing from the scope of thisiinvention W-hatI claim is:
